another question tho, i noticed that there are two types of tail lights for the 135i the stock one that has three horizontal red lines and the other one which has two rotated L shaped "in a way" bold lines. r the second ones aftermarket or are they the tail lights our the 1M? and how can i get them?

Those are LCI (Facelift) tail lights. Those lights can be ordered from here if you want the blackline (smoked) version
